Long pile fur to use in addition to the Z-COVER fabric.

In comparison to the short pile fur Z-FUR-SH, the efficiency is improved by 4-5 dB in the critical range 20-200Hz with a slight acoustical degradation of 1-2dB of the lowest and highest frequencies.

The main inconvenient is mostly an increase of the volume.
